Starting today and running through next week, Blumenthal will be screening at the JW3 cinema in London. You can book tickets here. This release comes courtesy of the ever-awesome and ever-supportive UKJFF. Can't say enough good things about this festival and organization. I would suggest that any indie filmmaker put a Jewish character in their film if only to screen with them and get into the powerful international machine that is the UKJFF.
If you are British, but inclined to watch Blumenthal from the comfort of your own home rather than partaking in the cinema experience, you can also see the film on iTunes UK. Check it out!
